Introduction
To analyze COVID-19 mortality in cancer patients and associated factors such as age, sex, type of insurance, situation at COVID-19 diagnosis, and cancer histology during the pandemic at a cancer center in Brazil.
Methods
Cross-sectional study carried out from April 02, 2020 to August 31, 2020 at A.C. Camargo Cancer Center (ACCCC), in São Paulo, Brazil. Cases were extracted from the Hospital Cancer Registry. COVID-19 lethality rates by histology were calculated; multiple logistic regression was used to identify factors associated with COVID-19 mortality. The log-rank test was applied to compare the survival curves for each variable.
Results
Of the 411 patients analyzed, 51 (12.4%) died due to COVID-19. Death occurred at an average age of 63 years. The fatality rate was higher for lung (0.333) and hematological (0.213) cancers and was associated with age over 60 years. The greatest chances of death from COVID-19 were in cases of lung (odds ratio, OR, 4.05, 95% confidence interval, CI 1.33–12.34) and hematological (OR 2.17, 95% CI 0.96–4.90) cancers, and in patients currently undergoing cancer treatment (OR 2.77, 95% CI 1.25–6.13). There were no statistical differences in survival by sex, age group, type of insurance, situation at the diagnosis of COVID-19, and histology of cancer for COVID-19.
Conclusions
Mortality due to COVID-19 in cancer patients is heterogeneous. These findings reinforce the need for individualized strategies for the management of different types of cancer that reduce the risk of death from COVID-19.
Background
To investigate the excess of deaths by specific causes, in the first half of 2020 in the city of São Paulo-Brazil, during the COVID-19 pandemic.
Methods
Ecological study conducted from 01/01 to 06/30 of 2019 and 2020. Population and mortality data were obtained from DATASUS. The standardized mortality ratio (SMR) by age was calculated by comparing the standardized mortality rate in 2020 to that of 2019, for overall and specific mortality. The ratio between the standardized mortality rate due to COVID-19 in men as compared to women was calculated for 2020. Crude mortality rates were standardized using the direct method.
Results
COVID-19 was responsible for 94.4% of the excess deaths in São Paulo. In 2020 there was an increase in overall mortality observed among both men (SMR 1.3, 95% CI 1.17–1.42) and women (SMR 1.2, 95% CI 1.06–1.36) as well as a towards reduced mortality for all cancers. Mortality due to COVID-19 was twice as high for men as for women (SMR 2.1, 95% CI 1.67–2.59). There was an excess of deaths observed in men above 45 years of age, and in women from the age group of 60 to 79 years.
Conclusion
There was an increase in overall mortality during the first six months of 2020 in São Paulo, which seems to be related to the COVID-19 pandemic. Chronic health conditions, such as cancer and other non-communicable diseases, should not be disregarded.
OBJECTIVE:Immunosuppressed patients are at risk of microsporidiosis, and this parasitosis has an increased rate of dissemination in this population. Our objective was to evaluate the presence of microsporidiosis and other intestinal parasites in rheumatic disease patients undergoing anti-tumor necrosis factor/disease-modifying anti-rheumatic drug treatment.METHODS:Ninety-eight patients (47 with rheumatoid arthritis, 31 with ankylosing spondylitis and 11 with psoriatic arthritis) and 92 healthy control patients were enrolled in the study. Three stool samples and cultures were collected from each subject.RESULTS:The frequency of microsporidia was significantly higher in rheumatic disease patients than in control subjects (36 vs. 4%, respectively; p<0.0001), as well as in those with rheumatic diseases (32 vs. 4%, respectively; p<0.0001), ankylosing spondylitis (45 vs. 4%, respectively; p<0.0001) and psoriatic arthritis (40 vs. 4%, respectively; p<0.0001), despite a similar social-economic class distribution in both the patient and control groups (p = 0.1153). Of note, concomitant fecal leukocytes were observed in the majority of the microsporidia-positive patients (79.5%). Approximately 80% of the patients had gastrointestinal symptoms, such as diarrhea (26%), abdominal pain (31%) and weight loss (5%), although the frequencies of these symptoms were comparable in patients with and without this infection (p>0.05). Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis disease activity parameters were comparable in both groups (p>0.05). The duration of anti-tumor necrosis factor/disease-modifying anti-rheumatic drugs and glucocorticoid use were also similar in both groups.CONCLUSION:We have documented that microsporidiosis with intestinal mucosa disruption is frequent in patients undergoing concomitant anti-tumor necrosis factor/disease-modifying anti-rheumatic drug therapy. Impaired host defenses due to the combination of the underlying disease and the immunosuppressive therapy is the most likely explanation for this finding, and this increased susceptibility reinforces the need for the investigation of microsporidia and implementation of treatment strategies in this population.
In 2015, two new species related to the
Staphylococcus aureus
were proposed. We describe five isolates of the new species
Staphylococcus argenteus
cultured from human cases of bacteremia and skin and soft tissue infections. This is the first report of
S. argenteus
, from South America, causing community-acquired and nosocomial infections.
